Security Level 2 certification for Moxa NPort 6000-G2 Series

Moxa sets new security benchmark for serial device servers with world’s first IECEE 62443-4-2 certification

Moxa Inc., a trusted leader in industrial communications and networking, has added another significant milestone to its growing portfolio of cybersecurity achievements. The NPort 6000-G2 Series has become the world’s first serial device server to attain the IECEE 62443-4-2 Security Level 2 certification.

This achievement underscores Moxa’s dedication to securing the often-overlooked connectivity edge of industrial networks, ensuring legacy serial devices are protected with the same rigorous standards as modern IP-based infrastructure.

As industries accelerate towards digitalisation, the convergence of IT and OT networks has exposed critical operational assets to new cyberthreats. Many of these assets communicate via legacy yet stable and industry-standard serial protocols (RS-232/422/485). However, these protocols were designed for reliability in an era before interconnected networks and modern cybersecurity were a primary concern. The NPort 6000-G2 Series acts as a critical security gatekeeper for edge assets such as PLCs, meters, and consoles, enabling asset owners to keep their trusted infrastructure while meeting stringent security mandates.

Its launch marks a pivotal moment that completes Moxa’s "Edge-to-Core" security coverage. This certified defense-in-depth ecosystem now spans from the NPort 6000-G2 at the device level, to the EDS-G4000 switches and EDR-G9010 secure routers at the network core, and finally the UC-8200 Series industrial computers.

Bureau Veritas (BV), a world leader in testing, inspection, and certification, officially validated this achievement. It confirms the NPort 6000-G2 Series meets the strict technical security requirements for components in Industrial Automation and Control Systems (IACS).

"We are honored to witness Moxa achieving the world’s first IECEE 62443-4-2 certification for a serial device server," said David Hsueh, Cyber Director of Technology Products Taiwan at Bureau Veritas.
